Hinges and Heel-Plates, of which the following` is speciication.

The object of the invention is to provide a new and novel means for connecting the switch point to a section of the main track in railroad construction. To this end the invention comprises a chair. in which the end of the main track section seats, this chair being formed with a heel plate for the vpivoted end of the switch point. An angle bar clamps against the main track section and to the chair and it and the heel plate support a pin on which the switch is pivoted by means of an eye formed at its base flange.

Illustrated and described in a specific embodiment, the invention is not to be restricted to such. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in

so far as such changes or alterations are compatible in spirit with the annexed claims.

The same numerals of reference designate the same parts throughout the several figures of the drawings, wherein:

Figure 1 is a view in side elevation of the invention.

Fig. 2 is a top plan view.

Fig. 3 is a section on the line 3`-3 of Fig. l.

Fig. 41 is a section on the line 4-4 of Fig. 1.

Fig. 5 is a top plan view of the chair comprising a part oi the invention.

Referring to the drawings, there is shown that end of the rail section 1 to which the switch point 2 is connected. This end of the rail section consists in an appropriate chair comprising the base plate 3 and the base and web engaging section 4. The switch point 2 also rests in this chair at its pivotend, the base plate of the chair being the heel plate of the switch point. An angle bar 5 is secured to the rail section 1 on the opposite side :trom the section 4 of the chair, bolts 6 being employed for the purpose of such attachment. The angle bar is shorter than the section 4. of the chair but is of suflicient length to extend beyond the section 1 and overlap the pivot end of the switch point 2. The inner face of the web engaging portion of the angle bar .5 at that end which overlaps f the switch Vpoint is beveled or tapered olf as indicated at 7 The flange engaging portion of the angle barf and the base plate 3 are eachtormed with a hole 8, while the base flange of the switch point 2 is simply formed with a hole 9 which registers with the holes 8, a pin 10 being passed through the three to provide a pivot point for Vthe switch point 2. The pinV 10 is enlarged in diameter where it passes through the base flange of the switch point. 'Shoulders are thus formed on opposite sides of the enlarged portion and :bear respectively against the base flange 3 andV the angle bar 5. Vertical movementot the pin is'thusfprevented and it is maintained in place to provide the pivot for the switch point.

Base plate 3 of the chair is, as indicated in Figs. 2 and 5 of the drawings, tapered in the direction of its length on one side, that part of the base plate receiving the switch point being the widest, so that there may always be a heel portion for the base of the switch point toY rest upon when the switch point is swung to either of its two positions which it is necessary for it to assume in practice.

The chair is cut away as indicated at 11 to provide a space for spikes in attaching the device to a tie'and the chair is formed at the base plate with an opening 12 eX- tending as shown at 13, and an opening at the side of the base plate, so-that an implement may be inserted between the end of the rail section 1 and the switch point to clear the two from dirt which may be bef tweenthem. This dirt may be forced vdown through the opening 12. Y

Obviously in operating the switch point it swings on the pin` as a pivot the portion 14 of the chair serving to limit the Switch point to a position in alinement with the rail section 1 and the beveled portion 7 of the angle bar 5 permitting the switch point to swing inwardly to a position at an angle with reference to the section 1.

The invention having been described, what is claimed as new and useful is:

Al. In a device of the kind described, the combination with a rail section, of a switch point having one end disposed adjacent the end of .the rail section, a chairrin which the ends of the rail section and switch point seat and comprising a base plate and a b ase flange of the angle bar and through theV flange of the switch point and through the base plate, whereby the switch point is pivotally connected `to the chair and to the angle bar forthe purpose specified.`

2. In a device of the kindydescribed, the combination with a rail section, of a switch point having one end disposed adjacent the end of the rail section, a chair in which the ends of therail section and switch point seat and comprising a base plate and a base and web engaging section, an angle bar disposed against the rail sectionand overlapping `the end of the switch point, means securing the angle bar, therail section and the web engaging section of the chair together, and a pin passing through one flange j of the angle bar and through the base plate and having an enlarged intermediate'portion bearing respectively against the base point having their twol ends adjacent each other, of a chair comprising a base plate and a web flange engaging portion, the rail sec.- tion and the switch point being seated in the chair and disposed against the web engaging portion thereof, an angle bar disposed against the rail section and overlapping the adjacent end of the switch point,

Vmeans securing the web engaging section,

the rail section and the angle bar together,

and a pivotal connection between the switch point and angle bar and base plate,` the base plate being :t'orinedkv with an opening l therein disposed below the adjoining ends 'of the rail section and the switch point and eX- tending laterally of the base plate. and opening through the side of the latter below the base and web engagingvportion of thechair, wherebjT foreign matter between the rail sec tion and the switch point may be ejected.-
